Description

Child safety seat

The invention relates to a child safety seat.

Child safety seats are generally used in cars, which can moderately limit the displacement of children in the event of accidental collisions. It is widely known that placing a child safety seat facing backwards in a car provides even more protection because it spreads the impact on larger parts of the body (i.e. the child's head and chest). Therefore, safety experts and car seat manufacturers usually recommend that children under the age of two ride the car in a back-facing posture. When the child grows up, change to a forward attitude and ride in the car.

The installation of child safety seats usually requires a car seat belt or a body belt separately provided in the car seat to fix the child safety seat to the car seat. As a result, installing a child safety seat can be difficult because when a caregiver pulls a car seat belt, he must enter the car and press down on the child car seat.

When the second belt clip 134 is in the released state, the surface 134A is erected on the surface 104A of the casing; when the second belt clip 134 is in the clamped state, the surface 134A is adjacent to the surface 104A of the casing. In addition, the housing surface 104A may further be provided with a second groove 152 spaced from the first groove 148, and the second band clamp member 134 may have a portion thereof (for example, the surface of the band clamp member 134) when it is clamped. 134A) received in the second groove 152. When the second band clamp 134 is in a clamped state, the surface 134A of the second band clamp 134 can press the fixing band 120 passing through the two second perforations 116, thereby curling the fixing band 120 and providing tension to the fixing band 120. The child safety seat 100 can be fastened to a car seat.

In order to facilitate the installation of the fixing band 120, the spring action of the spring 138 can cause the second band clamp 134 to be displaced to a released state. The spring 138 may be a torsion spring and coaxially disposed with the second pivot axis P2. Both ends of the spring 138 are respectively fixed to the second belt clip 134 and the seat body 104.

Referring to FIGS. 1 to 3, the seat body 104 has a region 154 between the first and second grooves 148 and 152, and the first and second latches 142 and 144 can be assembled in the region 154. . The region 154 is, for example, a hollow protruding portion separating the first and second grooves 148 and 152, and the first and second latching members 142 and 144 can be assembled inside the hollow protruding portion. The first latch 142 can be pivotally connected to the seat body 104 by a pivot axis P3, wherein the pivot axis P3 is substantially parallel to the first and second pivot axes P1 and P2, and the second latch 144 can be pivoted by the pivot axis P4 and The seat body 104 is pivotally connected, and the pivot axis P4 is substantially parallel to the first and second pivot axes P1 and P2 and the pivot axis P3. The first and second latches 142 and 144 may be disposed adjacent to each other in the region 154 of the seat body 104.

The first and second latch members 142 and 144 can be separately operated to lock or unlock the first and second band clamp members 132 and 134 respectively. For example, when the first latch member 142 is engaged with the free end of the band clamp member 132, the first band clamp member 132 can be locked in a clamped state, and the second latch member 144 is engaged with the second band clamp member 134. At the end, the band clamp 134 can be locked in a clamped state. More specifically, the first latch 142 may protrude from a side of the hollow protrusion of the region 154 and a notch 156 (as shown in FIG. 3) provided with the first end edge 132C of the first band clip 132. Phase engagement, thereby preventing the first band clamp 132 from rotating about the first pivot axis P1, and locking the first band clamp 132 in a clamped state. The second latching member 144 may protrude from the other side of the hollow protrusion of the region 154 (that is, on the opposite side from which the first latching member 142 protrudes) and is disposed with the second end edge 134C of the second belt clip 134. The notches 158 (as shown in FIG. 3) are engaged with each other, so as to prevent the second belt clip 134 from rotating about the second pivot axis P2, so that the second belt clip 134 is locked in a clamped state.

Referring to FIG. 3, the first and second latch members 142 and 144 can be respectively displaced to a locked state by the action of a spring to engage with the first and second band clamp members 132 and 134 respectively. For example, the seat body 104 may be combined with a spring 160, and two ends 160A and 160B of the spring 160 are fixedly connected to the first and second latches 142 and 144, respectively. The spring 160 can urge the first and second latch members 142 and 144 to be displaced to the locked states, respectively, so as to be locked with the first and second band clamp members 132 and 134, respectively. In addition to using one spring, the present invention can also use two springs to be coupled to the first and second latches 142 and 144, respectively.

Referring to FIG. 1 to FIG. 3, the first belt clamping member 132 may be combined with a first actuating member 162, and the first actuating member 162 is exposed on the surface 132B. For example, the first actuating member 162 may be slidably connected with the first band clamp member 132 adjacent to the first end edge 132C of the first band clamp member 132. The first actuating member 162 is movable relative to the band clamp member 132 between the first position and the second position, wherein the first actuating member 162 is retracted toward the inside of the band clamp member 132 when in the first position. When the first moving member 162 is in the second position, it protrudes beyond the first end edge 132C of the first belt clip 132. When the first belt clamp 132 is in a clamped state, the sliding of the first actuator 162 from the first position to the second position can push the first latch 142 to move, thereby forcing the first latch 142 to disengage from the first latch 142. The first edge 132C is engaged, thereby unlocking the first belt clip 132. Two ends of the spring 164 may be connected to the first actuating member 162 and the first band clamp member 132, respectively. The spring 164 can cause the first actuator 162 to be displaced to the first position.

Similarly, the second band clamp member 134 can be combined with a second actuating member 166, and the second actuating member 166 is exposed on the surface 134B. For example, the second actuator 166 may be slidably connected with the band clamp 134 adjacent to the second end edge 134C of the second band clamp 134. The second actuating member 166 is movable between the first position and the second position relative to the second band clamp 134, wherein the second actuating member 166 is in the first position toward the second band clamp 134 It is retracted internally, and when the second actuating member 166 is in the second position, it protrudes beyond the second trailing edge 134C of the second band clamp member 134. When the second band clamp 134 is in the clamped state, the sliding of the second actuating member 166 from the first position to the second position can push the second latch 144 to move, thereby forcing the second latch 144 to disengage from the first The second edge 134C is engaged, thereby unlocking the second belt clip 134. Two ends of the spring 168 may be connected to the second actuating member 166 and the second band clamp member 134, respectively. The spring 168 can cause the second actuator 166 to be displaced to the first position.

The operation of the clamping mechanism 130 will be further described later. It is assumed that the child safety seat 100 is to be mounted on a car seat in a back-facing state. With the second belt clip 134 held in the clamped state, the caregiver can install and tighten the fixing belt 120 passing through the two first holes 114 by operating the first belt clip 132 separately. More specifically, the caregiver can force the first latch member 142 to disengage from the first band clamp member 132 by operating the first actuating member 162 to release the first band clamp member 132. After the first belt clamp 132 is released, it can be rotated from the clamped state to the released state. The force of the spring 136 on the first belt clamp 132 can help drive the first belt clamp 132 from the clamped state to the released state. State of rotation. Then, the fixing band 120 can pass through the two first perforations 114 laterally and pass through the space between the first band clip 132 and the case surface 104A. The caregiver can then rotate the first belt clip 132 toward the housing surface 104A to a clamped state, so that the first belt clip 132 presses down the fixing belt 120 into the first groove 148 of the seat body 104, thereby tightening固定 带 120。 The fixed band 120. When the first band clamp 132 reaches the clamped state, the spring 160 can force the first latch 142 to displace and engage with the first end edge 132C, thereby locking the first band clamp 132.

When the fixing belt 120 is to be released, the caregiver can release the first belt clip 132 by operating the first actuating member 162. After the first belt clip 132 is released, it can be rotated from the clamped state to the released state, thereby releasing the fixing band 120.

In addition, it is assumed that the child safety seat 100 is mounted on a car seat in a forward-facing state. With the first band clamp 132 held in the clamped state, the caregiver can operate the second band separately The band clip 134 is installed and tightened through the fixing band 120 passing through the two second holes 116. More specifically, the caregiver can force the second latch member 144 to disengage from the second band clamp member 134 by operating the second actuating member 166 to release the band clamp member 134. After the second band clamp 134 is released, it can be rotated from the clamped state to the released state. The force of the spring 138 on the second band clamp 134 can help drive the second band clamp 134 from the clamped state to the released state. State of rotation. Then, the fixing band 120 may pass through the two second perforations 116 laterally and pass through the space between the second band clip 134 and the case surface 104A. The caregiver can then rotate the second belt clip 134 toward the housing surface 104A to a clamped state, so that the second belt clip 134 presses down the fixing belt 120 into the second groove 152 of the seat body 104, thereby tightening固定 带 120。 The fixed band 120. When the second band clamp 134 reaches the clamped state, the spring 160 can force the second latch 144 to displace and engage with the second end edge 134C, thereby locking the second band clamp 134.

When the fixing belt 120 is to be released, the caregiver can release the second belt clip 134 by operating the second actuating member 166. After the second belt clip 134 is released, it can be rotated from the clamped state to the released state, thereby releasing the fixing band 120.

4 and 5 are schematic diagrams illustrating a child safety seat 100 according to another embodiment of the present invention. The child safety seat 100 shown in FIGS. 4 and 5 includes a clamping mechanism 130 as described above. However, the embodiment of FIGS. 4 and 5 is different from the previous embodiment in that the first belt clip 132 further includes two first retaining members 172, and the second belt clip 134 also includes two first Second block protector 174.

Referring to FIG. 4 and FIG. 5, the two first blocking members 172 are respectively disposed on the left and right sides of the plate body 146 of the first band clamp member 132, and are respectively located adjacent to the two side walls 112. The two first shields 172 can be fixed to the left and right sides of the plate body 146 respectively. For example, the two first shields 172 can be fixed to the left and right sides of the plate body 146 through the two arm portions 176. When the first belt clip 132 is pivoted between the released state and the clamped state, the two first blocking members 172 and the first belt clip 132 move synchronously to open or shield the two first perforations 114 respectively. In particular, the two first shields 172 substantially shield the two first perforations 114 when the first band clamp 132 is in the clamped state (as shown in FIG. 5), and the two first shields 172 When a belt clip 132 is in a released state (as shown in FIG. 4), the two first through holes 114 are substantially opened. When the two first blocking members 172 cover the two first perforations 114, a narrow gap may be left between the edge of each first blocking member 172 and the edge of the corresponding first perforating 114 for the fixing band to pass through. Therefore, when the child safety seat 100 is installed in the The blocking member 172 substantially shields the two first perforations 114, and the fixing band can still pass through the two first perforations 114 and be clamped by the first belt clip 132.

Similarly, the two second guards 174 are respectively disposed on the left and right sides of the plate body 150 of the second belt clip 134, and are respectively located adjacent to the two side walls 112. The two second shields 174 can be fixed to the left and right sides of the plate body 150 respectively. For example, the two second shields 174 can be fixed to the left and right sides of the plate body 150 through the two arm portions 178. When the second band clamp 134 is pivoted between the released state and the clamped state, the two second guards 174 and the second band clamp 134 move in synchronization to open or shield the two second perforations 116 respectively. . The two second guards 174 substantially shield the two second perforations 116 when the second belt clamp 134 is in the clamped state (as shown in FIG. 5), and the two second guards 174 are in the second belt. When the clip 134 is in the released state (as shown in FIG. 4), the two second through holes 116 are substantially opened. When the two second guards 174 cover the two perforations 116, a narrow gap may be left between the edge of each second guard 174 and the edge of the corresponding second perforation 116 for the fixing band to pass through. Therefore, when the child safety seat 100 is installed in a forward direction, even if the two second guards 174 substantially cover the two second perforations 116, the fixing belt can still pass through the two second perforations 116 and be clamped by the second belt. 134 clamping.

The first blocking member 172 and the second blocking member 174 can respectively close the two belt paths defined by the first and second perforations 114 and 116 so as to prevent the incorrect installation of the fixing band. For example, assuming that the child safety seat 100 is installed in a back-facing state, the caregiver only needs to operate the first belt clip 132, and the second belt clip 134 is maintained in a clamped state, so that the two second guards 174 are substantially shielded Two second perforations 116. In this way, the caregiver can be prevented from mistakenly passing the fixing band through the two second perforations 116.

If the child safety seat 100 is installed in a forward-facing state, the caregiver only needs to operate the second belt clip 134, and the first belt clip 132 will be maintained in a clamped state, so that the two first guards 172 substantially cover the two A perforation 114. In this way, the caregiver can be prevented from mistakenly passing the fixing band through the two first perforations 114.

The above-mentioned child safety seat is provided with a clamping mechanism, which is easy to operate, and can appropriately tighten the fixing band, so that the child safety seat can be fixed on the car seat in a back state or a forward state. In addition, the clamping mechanism may include safety measures that can shield the belt path of the child safety seat to prevent incorrect installation of the fixing belt.
